The very ritual practices that the New Atheists dismiss as costly, inefficient and irrational turn out to be a solution to one of the hardest problem… - Jonathan Haidt

Moral matrices bind people together and blind them to the coherence, or even existence, of other matrices. This makes it very difficult for people to consider the possibility that there might really be more than one form of moral truth, or more than one valid framework for judging people or running a society.

The effectance motive helps explain the progress principle: We get more pleasure from making progress toward our goals than we do from achieving them because, as Shakespeare said, “Joy’s soul lies in the doing.

"The "omnivore's dilemma" (a term coined by Paul Rozin) is that omnivores must seek out and explore new potential foods while remaining wary of them until they are proven safe. Omnivores therefore go through life with two competing motives: neophilia (an attraction to new things) and neophobia (a fear of new things). People vary in terms of which motive is stronger, and this variation will come back to help us in later chapters: Liberals score higher on measures of neophilia (also known as "openness to experience"), not just for new foods but also for new people, music, and ideas. Conservatives are higher on neophobia; they prefer to stick with what's tried and true, and they care a lot more about guarding borders, boundaries, and traditions."
